2023 Minibook X N100 - How to Encrypt Windows 11 System Drive

I would like to encrypt the Windows 11 Home (C:) drive with BitLocker, in case I lost it while travelling.

I navigated to System>Storage>Disks & volumes>Windows (C:)

When I clicked “Turn on Bitlocker”, it says "Failed to open the Bitlocker control panel. Error code: 0x80004005.

Is there a way to encrypt the Windows 11 Home system disk? Thank you in advance.
